Recent analysis by NPR reveals that the Centers for Disease Control and Prevention (CDC) has significantly reduced its communication efforts on infectious diseases, leaving many health professionals concerned about the agency’s ability to respond to outbreaks.
CDC’s Role in Public Health Communication
The CDC has long been the nation’s leading authority on health promotion, disease prevention, and preparedness. Traditionally, it has provided public guidance on health risks and how to prevent them. This has included frequent updates and alerts to health professionals about infectious threats.
However, in recent months, the CDC has scaled back its communication efforts. Health professionals report a decline in newsletters and a dramatic drop in social media outreach. According to NPR, staff reductions, particularly within the communications department, have hindered the CDC’s ability to respond swiftly to emerging threats like listeria, salmonella, and viruses such as measles and bird flu.
In fact, ProPublica highlighted that despite an ongoing measles outbreak across several states, relevant information from the CDC has been hard to locate.
Need for Timely Alerts
Many health professionals and the public are concerned about this decline in communication. While trust in the CDC has been shaken since the COVID-19 pandemic, experts argue that cutting back on alerts about infectious diseases is a troubling move. Experts emphasize the need for timely communication to help epidemiologists and public health personnel address outbreaks efficiently.
Vaccine Messaging and Policy Changes
In addition to staffing issues, the CDC may be facing a shift in its vaccination policies. For decades, the agency has worked to promote vaccinations against diseases like measles and influenza. However, recent changes have raised questions about the agency’s stance on vaccination.
ProPublica’s difficulty in finding information on measles prevention highlights a broader issue: the CDC’s messaging on vaccinations may now be influenced by external factors. Health and Human Services (HHS) Secretary Robert F. Kennedy Jr., a prominent vaccine skeptic, has created confusion with recent policy reversals. On May 27, 2025, Kennedy announced that HHS no longer supports COVID-19 vaccination recommendations for pregnant women, a policy the CDC had previously endorsed. The decision has left pregnant women and their healthcare providers uncertain about the risks and benefits of vaccination.
Conclusion
The CDC’s reduced communication on infectious diseases, combined with recent shifts in vaccination messaging, has raised alarms among health professionals and the public. As the agency navigates these changes, it remains critical to ensure that health alerts and guidance reach those who need them most—especially during outbreaks.
